Spontaneous emission factor in oxide confined vertical-cavity lasers
We report on measurements of the spontaneous emission factor for oxide-confined InGaAs vertical cavity surface emitting lasers. The spontaneous emission factor is determined as a function of the active layer volume from the measurement of small-signal harmonic distortion at threshold. For a 333 mm oxide aperture device we obtain spontaneous emission factor of 4.2•10 at room temperature. © 1997 ...
متن کاملCold-cavity measurement of optical loss from oxide-confined vertical-cavity surface-emitting lasers
Microcavity laser design and performance optimization requires a quantitative knowledge of the cavity optical losses. A generalized method using sub-threshold spectral measurements matched to model calculations is demonstrated to determine optical loss in microcavity lasers. Cold-cavity spectral characteristics are used to extract the size-dependent optical loss for small diameter oxide-confine...
متن کاملDifferential carrier lifetime in oxide-confined vertical cavity lasers obtained from electrical impedance measurements
Differential carrier lifetime measurements were performed on index-guided oxide-confined vertical cavity surface emitting lasers operating at 980 nm. Lifetimes were extracted from laser impedance measurements at subthreshold currents, with device size as a parameter, using a simple small-signal model. The carrier lifetimes ranged from 21 ns at 9 mA, to about 1 ns at a bias close to threshold. F...
متن کاملTwo-Dimensional Photonic Crystal Confined Vertical-Cavity Surface-Emitting Lasers
The two-dimensional photonic crystal (2-D PhC) structure has been investigated as a method for lateral mode control of vertical-cavity surface-emitting lasers (VCSELs). The 2-D PhC structures were designed using an equivalent index model developed for photonic crystal fibers combined with a plane wave expansion method. The etching depth dependence of the PhC structure was incorporated for the f...
متن کاملAnomalous above-threshold spontaneous emission in gain-guided vertical-cavity surface-emitting lasers
Anomalously large decrease in spontaneous emission is observed in gain-guided vertical-cavity surface-emitting lasers after the onset of lasing. By analyzing two-dimensional profiles of the lasing mode and carrier density, we found that this unexpected phenomenon originates from the contraction of transverse lasing mode size. Under the condition of the constant modal gain, it is explained that ...
